Problems solved by technology

[0003] The present invention aims to solve the problem that the surface smoothness of the masterbatch is not smooth enough when the existing polyolefin molding die processes the ultraviolet light crosslinked polyolefin masterbatch, and a large amount of moisture is attached to it, so that the moisture cannot be removed through normal air-cooling and drying, resulting in a decrease in production rate. Due to the problem of production decline, a new type of molding die for polyolefin masterbatch production line was proposed

Abstract

The invention provides a forming mold for a novel polyolefin master batch production line, relating to a plastic granule processing molding part and aiming at solving the problems that the surface smoothness of the master batch is poor, a great amount of moisture is attached and cannot be removed by a normal air cooling and drying method, the production rate is reduced and the yield is reduced when the existing polyolefin forming mold is used for processing the ultraviolet light crosslinked polyolefin master batch. The forming mold for the novel polyolefin master batch production line comprises an opening mold plate and a mold body, the opening mold plate is also provided with a fixing hole connected with the mold body, a flow concentration cavity, a transition section and a forming hole are sequentially arranged at the center of the opening mold plate in a thickness direction from inside to outside, the flow concentration cavity, the transition section and the forming hole are communicated and penetrate through the opening mold plate, and the coaxial line of the flow concentration cavity, the transition section and the forming hole is coincided with the central line of the opening mold plate, the flow concentration cavity is a tapered hole, the transition section is a cylindrical hole, the forming hole is a tapered hole, and the diameter of the narrow mouth of the flow concentration cavity is the same as that of the diameter of the narrow mouth of the forming hole. The forming mold for the novel polyolefin master batch production line is suitable for production of the polyolefin master batch in the chemical equipment field.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to plastic particle processing molding parts. Background technique [0002] In the production process of polyolefin masterbatch, the structure of molding mold seriously affects the surface and production speed of masterbatch molding. The traditional plastic particle mold is composed of a manifold and a molding port, such as attached image 3 shown. This traditional structure can meet the production demand when processing ordinary plastic particles, but when processing UV cross-linked polyolefin masterbatch, due to the pressure rise of UV cross-linked polyolefin passing through the manifold, the material at the exit of the forming hole Excessive expansion, the radial expansion rate and the longitudinal traction rate cannot be coordinated, resulting in insufficient smoothness of the surface of the masterbatch, a large amount of moisture attached, unable to remove moistur...
